The Detroit Tigers would like to add a bat before the trade deadline, but with four quality outfielders and an MVP-caliber first baseman, there are not a lot of open positions on the Tigers starting lineup.

Shortstop, however, is certainly wide open though, and according to FoxSports.com, the Tigers may look to a familiar trade partner in their quest to improve their middle infield.

July 5, FoxSports.com:The Tigers are in the market for middle infield depth and have shown interest in Diamondbacks shortstop Stephen Drew, major league sources told FOXSports.com.

Drew would be an offensive upgrade for the Tigers, who have had the
second-worst shortstop production in the American League (.586 OPS). He
would also be a long-term fit. Detroit doesn't have a set No. 2 hitter
or everyday shortstop for the 2011 season; Drew, who won't be a free
agent until 2012, could fill both roles.

By acquiring middle infield depth now, the Tigers would effectively
obtain an insurance policy to use if Guillen goes on the disabled list
after the trade deadline. Other trade possibilities include Willie Bloomquist (Royals), Mike Fontenot (Cubs) and Ryan Theriot (Cubs), but it's unclear if the Tigers are involved in active discussions on those players.

Drew, who has missed time recently with a sore knee, is batting .268 this season with four home runs and 28 RBIs. The 27-year-old left-handed batter is a career .270 hitter and hit 21 home runs in 2008 (though only 12 last season).
